GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(444, 828) = 30636
GCD(444, 828) = ( 444 x 828 ) / 30636
= 444 / 828
= 444
Step2:
LCM(12, 778) = 4668
GCD(12, 778) = ( 12 x 778 ) / 4668
= 12 / 778
= 12
Step3:
LCM(2, 561) = 1122
GCD(2, 561) = ( 2 x 561 ) / 1122
= 2 / 561
= 2
So, Greatest Common Divisor of 444, 828, 778, 561 is 1
